Avril E 4 O g by leaving a space 64 for draining purposes.

The sashes are locked in the usual manner by two cooperating lock members 65 and 66.

The lower sash side frames 67, Fig. 2, have each a vertical flange 68 adapted to engage behind the T-rail 17 on the inside thereof, and an inner flange 69 adapted to. engage in the groove 15 in the side jambs 5.

Referring now to Figure 1 it will be seen that when the window is closed, the two sashes engage with a three point contact construction because of the engagement of the upper sash elements 39, 40 and ll with the lower sash elements 51, 52 and 53, the parts being forced together by the lock -66.

At the top of the window there is also a three point closing contact because of the engagement of the wings 37 and 38 of the movable member 35 with the upper jamb members 23 and 21, together with the third engagement point between the members 33 and 25. At the bottom there is a two point engagement contact between the wings 61 and 62 of the movable member 59 with the sill members 7 and 8.

WVhen the lock 65-66 is unlocked, the upper sash lower frame and the lowersash upper frame naturally spring apart or are loosened so as to move easily. If now the lower sash is raised, it will be seen that there is no binding to overcome. The raising movement naturally and automatically causes the movable member 59 to tilt counter clockwise thereby automatically disengaging the wing" 62 from any binding contact with the flange 8. Similarly, when the upper sash is lowered, the

tilting action of the pivoted member 35 results in an automatic disengagementof said member with the top jamb members21- and 23, and in addition permits easy sliding disengagement between the flanges 33 and 25.

On the other hand, when the upper sash is moved up into closing position, the upward thrustof the pivot edge 34 will cause a counter clockwise movement of the two wing members 37 and 38 with the result that it will. engage the upper jamb tightly and also force the vertical flange 33 tightlyegainst the separating channel 25. i

The movable locking members '35 and 59 hang free on their respective pivot edges 34- and 58 upon which they are mounted by a sliding endwise movement. When the sashes are moved into closed positions, these members adjust themselves automatically into tight locking non-binding engagement with the corresponding cooperating parts of the jamb members.

Coming now to the sash side frames it will be seen from Figure 2, that the side frames 29 and 67 of the upper and lower sashes respectively, provide three points contact in cooperation with the sidejambs as follows. The upper sash member 44 engages the j amb member 18, and the member 43 engage the T- rail 17 at two points as shown. Similarly for the lower sash members of which 69 engages the j amb in the groove 15 while the member 68 makes a two point contact with the T- rail 17. I 7

It will therefore be seen that this invention provides a metal double hung window construction with three pointsof non-binding contact on all sides except at the bottom of the window. The movable contact members 35 and 59 afford particularly non-binding tight closure in an automatic manner by self adjustment. I

\Vhile the invention has been disclosed as applicable to a metal window nevertheless it will be understood that the principle of the invention is applicable to other forms of windows or doors, transoms and the like.

I claim: I 1. In a window structure of the character described, a window jamb, a window sash in movable relation thereto and means on said sash in pivotal relation to the sash providing tight contact between the said j amb and one edge of the sash when the latter is'closed.

' 2. In a window structure of the character described, a window jamb, a window sash in movable relation thereto and pivoted means on said sash automatically operable when the sash is closed for providing tight contact be tween the window jamb and one edge of the sash.

3. In a window structure of the character describecha window jamb, a window sash in movable relation thereto. and pivotedmeans on one edge of the said sash automatically operable when the sash is closed for providing tight contact between the window jamb and one edge of the sash.

4. In a window structure of the character described, a window jamb, a window sash in movable relation thereto, means providing tight closure between the sash and the jamb comprising a member pivoted on one edge of the sash and adapted to engage a fixed memher on the said jamb when the sash is closed.

5. In a windowstructure of the character described, a window jamb, a window sash in movable relation thereto and a member pivoted on one edge of the sash] and extending along the samethe length thereof providing tight closure between the said jamb and one edge of the sash when the latter is closed.

6. In a window structure of the character" described, a window jamb, a window sash in movable relation thereto, means on said jamb providing angularly disposed contacting walls and a member pivoted on said window sash on one edge thereof adapted to automatically engage said cont-acting walls to provide tight closure between the window sash and the jamb.

7. In a window structure of the character described, a window jamb, a window sash in movable relation thereto, means providing tight closure at a plurality of contacting points between the said jamb and sash comprising angularly disposed walls formed in said jamb, a contacting member pivoted on and along one edge of the sash and adapted to automatically engage the said walls.

8. In a window structure of the character described, a window jamb, a window sash in movable relation thereto, angularly disposed walls formed in said jamb, and a fixed member and a movable member on said sash arranged in parallelism along one edge thereof for engagement with said angular walls to afford tight closure between said sash and j amb.

9. A window structure of the character described, a window jamb, a wind-ow sash in slidable relation thereto, angularly disposed walls formed in the top section of said jamb, a fixed member and a movable member extending along the top of said sash and adapted to enter between and engage said angularly disposed j amb walls to afford tight closure at a plurality of points of engagement between the top of the jam'b and the top of the window sash.

10. Closing means for the top section of a Window janib and the top of a window sash comprising in combination angularly disposed spaced walls formed in the window jamb, a fixed member on the window sash adapted to engage one of said jamb walls and a movable member on said window sash adapted to automatically engage others of said jamb walls when the sash is closed and to exert a closing pressure on said fixed member.

11. Closing means for the top section of a window j amb and the top of a window sash comprising in combination angularly disposed spaced walls formed in the window j amb, a fixed member on the window sash adapted to engage one of said jamb walls and a movable member on said window sash adapted to automatically engage others of said jamb walls when the sash is closed and to exert a closing pressure on said fixed member, said fixed and movable sash members being arranged in parallelism along the top of the window sash.

12. Closing means for a window jamb and a window sash comprising in combination angularly disposed flanges formed in the jamb and a member pivoted on and extending along one edge of the window sash for automatic closing engagement with said jamb flanges.

13. Closing means for window sashes comprising in combination a pivot edge member on the sash, a closing member formed with a jamb portion for pivotal engagement with said pivot edge member and contacting portions to both sides of the said jamb portion, said closing member extending the length of the sash at one side thereof.

14. Closing means for window sashes comprising a member adapted to, be mounted on a window sash along one edge thereof and consisting of a centrally disposed grooved body portion and contacting wing portions extending therefrom to both sides for the purpose set forth;

15. In a window structure in combination with the window jamb an upper and a lower window sash and fixed means on said sashes providing tight closure at a plurality of points between said sashes and between the latter and the window jamb, and movable means on said sashes providing tight closure at other points between the sashes and the window jamb, said movable means being automatically operable upon the closing of the window sashes.
